You've gotten some great replies here!
-#1 rule IMHO- BE YOURSELF. Don't try to be somebody you're not. Hopefully that is a friendly, approachable maker that people are drawn to. The guys that try to be a salesman nearly always come off like a giant tool.
-I think the number of knives you should have is largely dependent on the style of knives you build. If a guy/gal does more simple stuff like small blades with a machine or bead-blast finish and simple thin scales, then having a lot of knives is fine. If a guy is shooting for a higher end market, then a lot of knives on your table makes it look like nobody wants/buys your stuff. For me and the type of stuff I make, I wouldn't want more than 10, but 5 or 6 is a good number.
-Stand up as much as you can. People that are sitting get walked past. I have SUPER flat feet and my feet get sore pretty quick just from standing in one spot... but I NEVER sat down during the entire 3 days of the ABS Expo in Texas a couple weeks ago.
-Even when you get bored to death- and you WILL.

Try to stay positive and happy. Guys that LOOK super bored, frustrated, mad.... get walked past.
-SMILE ---- A LOT.
-Greet everyone you can. You would be amazed at how many people you'll see that CLEARLY have
ZERO intention of stopping.... yet you smile and say, "How are you today?" that suddenly stop, look over your work, and often will end up talking to you for quite awhile.
***The last comment leads me to something that drives me nuts. I am always wishing I could know just what people at a show are thinking about. You'll see a guy who wouldn't stop and look at your stuff if you paid him, and he'll go directly to some other makers table and just "Ooooh and Aaaahhhh" over every knife on his table. It's hard to not wonder, "What didn't he like about my work" or "He must not like my face"
-If you take carbon steel knives, WIPE THEM DOWN ALL DAMN DAY!!! When I started I used almost only ATS-34. You could lay them out, not wipe them down, then pack them home away in a drawer without wiping them down, and they'd be fine. Do that with carbon blades and you'll have hundreds of pits in your blades. I don't even wait for the people to walk away. I wipe them down while talking to people--- it's a two fold thing---- 1.) A freshly wipe blade shows off your hard earned finish better 2.) Spit spots are directly from the devil and will eat into a blade in minutes, not hours.

:barf:
There are a few things that really hit Angi and I at the last show. Because of moving into a new house this past summer, we misplaced some stuff---- so at the show I did NOT have a sign (I recommend something simple and clean, not a 20' banner) nor did I have my business cards. It was amazing how many people said they nearly missed me without a sign and how many people actually ASKED for business cards. As frustrating as it feels when you have a guy walking through the show with his 4 and 5 year old sons both collecting 3-4 business cards from
every table.... it's more frustrating NOT having any to put out.
-Try not to eat AT your table if you can help it. Even super models are kind of ugly when they eat. Crusty knife makers are downright gross

Sometime we just can't help it though.... and if it's a choice between looking ugly while wolfing down a sammich or being dull and lethargic because you're starving.... choose ugly.
-Do NOT haggle!!! Work to figure out your prices and stick to them. Look a guy right in the eye when you tell him the price, and don't apologize (this is a do as I say, not as I do type of thing). Tim Hancock is always getting on me about this. And he does it masterfully. If I get somebody that asks if I negotiate, I just say, "No, these prices are firm. Thanks for asking." For some guys, it's just in their blood to haggle, even when they think your price is fair!!! If they really persist and don't want to drop it, I usually give them a very matter of fact explanation, something like- "I can appreciate you trying, but the thing is- I'm selling something that I made with my hands, from a pile of raw materials--- these aren't just a product that I ordered from a wholesaler and marked up before putting them out on the shelf--- and they aren't something I dug out of the garage to sell in a yard sale. These knives all represent a lot of blood, sweat, and tears--- so the prices are firm. Thanks

"
-Another thing I'm better at thinking of than doing

Mark everything clearly, but keep it simple. Folks see a lot of words (like this post of mine) and they just look past it and end up asking you things that all would have been answered if they read the card. But this is actually a good thing, as it induces more friendly conversation.
A very important thing that took me years to actually follow through with, is STAY AT YOUR TABLE. As a newer maker at your first shows, it's impossible to NOT WANT to wander around and meet everyone and look at stuff. However, you'll get home and have 20 people contact you saying, "I came by your table to meet you like 5 times and you were never there." You are there to put your face out there with your work. Let the show goers see that. Soak up the time with makers you can before the show, after the show, or during REALLY slow times. It sort of sucks. I stayed at my table in TX the entire day Friday and Sat, didn't even leave to pee!!! And only got away a little tiny bit on Sunday--- so I flat out missed seeing knives from many of my friends and getting to visit with them.... But remember you are at the show to sell your work.
Something I forgot. Don't be TOOOOO NICE to people. I have had several different shows where people parked themselves in front of my table and even end up putting their stuff on my table. That is so inconsiderate!!! If a guy spent $3,000 to be at a show, he needs to sell his knives. It's hard to do that if somebody blocks all the other show goers from seeing your work. I like bs'ing with people so much, and am VERY rarely confrontational, that I never say anything... but regret it later. If a guy or group of guys wants to park there, either invite them to sit behind your table and visit.... Or come up with a friendly way to let them know to move the hell on...

(and let me know what you come up with so I can use it too!

).
Have fun!!!
